Chapter 2 contemplates the environment’s ‘aesthetic’ value from philosophical perspectives. It outlines themes in the philosophy of environmental aesthetics, paying particular attention to Emily Brady’s integrated theory of environmental aesthetics. Brady attempts to marry subjective elements of aesthetic value – sensory, imaginative and emotional responses shaped by different cultures – with an objective ‘disinterest’ that permits comparisons for the purposes of environmental policy. The chapter then examines international legal scholarship on ‘aesthetic’ value as a term of international environmental treaties. Often framed by environmental ethics, the aesthetic value described by these scholars is one of several motivating states in their international agreement to protect the environment. This literature typically associates aesthetic value with natural beauty in ways rejected in the philosophy of environmental aesthetics as privileging only visual appreciations of nature, and critiqued as an Anglo-American ideal. The chapter argues that understandings of aesthetic value in international environmental law should be informed by philosophies of environmental aesthetics.
